This is my second stay at Ard's, the first was a year ago. I'm a frequent visitor to Bangkok and the only reason why I haven't stayed more often with Ard is because his place is usually booked.
Just as it was a year ago, the Ard's place is very clean and attention to comfort is on the level of a hotel. No other AirBNB place I've stayed in Bangkok comes close.
So do yourself a favour- If Ard's place is available for the dates you're looking at, stop searching and book it immediately!
